It’ll be 0=0 because when you solve for n it’s All real numbers, no you could have many solutions
Answer:
6x²+4x
Step-by-step explanation:
The given expressions are 3x²- 4x-4 and 3x²+8x+4.
We need to add these two expressions.
3x²- 4x-4 + 3x²+8x+4 = 3x² + 3x² -4x+8x-4+4
= 6x²+4x
On adding the given expressions, we get the value as 6x²+4x. Hence, the sum of the given expressions is equal to 6x²+4x

Answer:
0.79 Watts
Step-by-step explanation:
2 hours is 2 * 60 = 120 minutes
If you take 8 minutes per mile, you can run:
120/8 = 15 miles in 2 hours
Per mile calories consumption is 91, so in 15 miles:
91 * 15 = 1365
Average Power Output is Energy by Time
Also, calories to joules is:
1 Calorie = 4.184 Joules
So 1365 calorie is:
1365 * 4.184 = 5711.16 Joules
and 2 hours in seconds is 2 * 60 * 60 = 7200 seconds
Now
Average Power Output = 5711.16/7200 = 0.79 Watts
